Nitrogen fixation is surprisingly high in coastal waters and may play a larger role than expected in carbon dioxide (CO2) uptake in these waters, a new study led by Duke University scientists shows.

Climate change is shifting the energy in the atmosphere that fuels summertime weather, which may lead to stronger thunderstorms and more stagnant conditions for midlatitude regions of the Northern Hemisphere, including North America, Europe, and Asia, a new MIT study finds.

One of the largest field experiments ever conducted is providing the best evidence yet in support of a key Darwinian theory—that interactions between species are stronger toward the tropics and at lower elevations.

There is enough room in the world’s existing parks, forests, and abandoned land to plant 1.2 trillion additional trees, which would have the CO2 storage capacity to cancel out a decade of carbon dioxide emissions, according to a new analysis by ecologist Thomas Crowther and colleagues at ETH Zurich, a Swiss university.

Tropical Depression 02W has organized and strengthened into a tropical storm.

Fossil fuel combustion is the main contributor to black carbon collected at five sites around the Arctic, which has implications for global warming, according to a study by an international group of scientists that included a team from Baylor University.

The mesoscale activities (or mesoscale structures) in the ocean possess huge energy. 

The ice‐covered season plays an important role in the development of river channels, a new study from the University of Eastern Finland shows. 

Although conventional wisdom suggests that poor countries are more likely to bear a disproportionate burden of a worldwide carbon tax on fossil fuels used for electricity and transportation, the potential consequences of such a tax would vary depending on several factors, says new research co-written by a University of Illinois energy and environmental policy expert.

Total human carbon dioxide emissions could match those of Earth’s last major greenhouse warming event in fewer than five generations, new research finds.
